Using ‘higher-tier’ emission factors in National Greenhouse Gas Inventories is essential to improve quality and accuracy when reporting carbon emissions and removals. Here we systematically reviewed 736 data across 249 sites (published 2003–2020) to derive emission factors associated with land-use change in Indonesian mangroves blue carbon ecosystems. Four management regimes—aquaculture, degraded mangrove, regenerated mangrove and undisturbed mangrove—gave mean total ecosystem carbon stocks of 579, 717, 890, and 1061 Mg C ha−1 respectively.

A new policy brief from leading experts at the Centre for International Forestry Research-World Agroforestry (CIFOR-ICRAF) and IPB University, as a part of the Center for Global Sustainability’s (CGS) Indonesia Program new guest policy brief series, provides an overview of the crucial interconnection between bioenergy and land use, focusing specifically on the production and employment of biomass for bioenergy and biomaterial. This guest analysis evaluates four case studies to understand sustainable biomass management methodologies.

Sweetpotato (Ipomoea batatas) originated in Central America or north-western South America from where it was introduced to Europe, Africa, Asia and North America in more recent times. Sweetpotato is now cultivated in nearly all parts of the tropics and sub-tropics as well as in the warmer parts of the temperate regions (CIP, 2019). This is because Sweetpotato is a dry-land crop, tolerant to a wide range of edaphic and climatic conditions. It is more tolerant of cold than other tropical root and tuber crops, hence, it can be grown at altitudes as high as 2500 m.

Increased reliance on fertilizers and pesticides in rice production has proven unsustainable and ineffective due to soil depletion and pesticide-induced pest outbreaks, rising fertilizer costs, and the negative effects of pesticide and fertilizer use on human health and the environment. The integrated rice-fish system offers a large range of environmental, economic, and social benefits by improving diversification, intensification, profitability, and sustainability through the complementary utilization of land and water uses.

Are the forest conservation practices sustained after Payment for Environmental Services (PES) programmes end? Using a sample of 268 (former) PES recipients and non-recipients from the Budongo-Bugoma PES programme in Western Uganda, we employ the before-after-control–intervention (difference-in-difference) approach to estimate the PES programme outcome on their privately owned forests. PES is associated with less deforestation during the operational period, but the link has vanished four years after programme termination.

Moth bean (Vigna aconitifolia) is an orphan legume of Vigna genus, exhibiting wide adaptability and has the potential to grow well in arid and semi-arid areas, predominantly across different eco-geographical regions of Asia, particularly the Indian subcontinent. The inherent adaptive attributes of this crop have made it more tolerant towards a diverse array of abiotic and biotic stresses that commonly restrain yield among other Vigna species.

The Department of Crop Production coordinated with the International Rice Research Institute in Vietnam to develop this technical guideline for rice-producing provinces in the Red River Delta. The guideline focused on reducing inputs, improving efficiency, reducing greenhouse gas emissions and adapting to climate change for rice production.

Context

An innovation brief has been developed to facilitate the scaling of the Smart-Valleys approach for land and water development in inland valleys. The innovation brief presents how to implement the Smart-Valleys approach and its effects on rice yield and farmers’ income, as well as the users and the factors that affect the adoption of the approach.
